Why does the pump decay when connected in parallel?
When two pumps are connected in parallel, the flow rate is less than two of the rated flow of the pump. That is because of the loss of the pipeline and the incomplete sealing of the one-way valve (backflow) and the maximum capacity limit of the pipeline. The solution is to increase the diameter of the supervisor, check whether the one-way valve is completely sealed, whether the inlet and outlet pipe is blocked or not, and reasonably reduce the elbow and the valve.
Because a water pump has reached the rated parameters, the parallel is only "superfluous".
Pump parallel mainly solves the problem of insufficient flow. After parallel, the flow is two and the sum of the pumps. When the flow rate increases, the pressure loss of the pipeline will increase, so the water pump flow in parallel will not be the sum of the two pump flow, but less than the sum of the flow rate. The solution is to increase the diameter of the water supply pipe, reduce the angle bend and shorten the distance.........
